SIGNAL.

Application filed Isebrnary 5, 1924. Serial No. 690,839.

To all whom it may concern:

Be it known that 1, DAN E. SEEMAN, a citizen of the United States, residing at Republic, in the county of Fayette and State of Pennsylvania, have invented new and useful Improvements in Signals, of which the following is a specification.

This invention relates tosignals, and more particularly to an alarm to be used in connection with automobiles.

One of the main objects of the invention is to provide an alarm in the form of a bell which is operated by the action of the automobile engine, and which may be quickly and readily applied at very small cost. A

further object is to provide a device of this character of simple and inexpensive construction. Further objects will appear from the detail description.

In the drawings Fig. 1 is an elevation of the device as applied, the engine being shown fragmentarily Fig. 2 is a section taken substantially on F line 22 of Fig. l. i

The device includes a gong or bell 1 mounted upon a post 2 carried by a plate 3 provided with openings for reception of screws 4 or other suitable securing elements .by means ofwhich the plate can be secured to a supporting structure or to the engine A of an automobile. A securing screw 5 passes through a slot 6 provided in gong 1 for this purpose and is threaded into post 2.

". This provides simple and efiieient means for securing the gong in position and for adjusting it toward or away from a cylinder 7 provided at the outer end of plate 3. A cylindrical striker 8 is 'slidably mounted in cylinder 7 and gong 1 is so adjusted that, when the striker is projected, it will contact with the gong so as to vibrate or sound the same. The cylinder 7 is provided in its outer end with a reduced chamber9 from which extends a neck 10 to which is secured, by means of a suitable connection 11, one end of a tube 12. The other end of this tube is connected to an outlet nipple 13 of a valve 14 of a known type which is threaded through the top wall of one cylinder of cylinder head B thus establishing communication between the valve 14 and the interior of the cylinder. Valve let is controlled by means of a flexible member 15 which is secured to one end of a control lever 16 of the I valve. The valve is normally closed so as to shut off communication between cylinder 7 and the engine cylinder. By means of member 15 lever 16 can be moved into position to open the valve when it is desired to operate the signal.

WVhen valve let is opened communication is established between the engine cylinder and cylinder 7 so that, upon the suction stroke of the piston in the engine cylinder striker 8 is drawn into cylinder 7 and upon the compression stroke of the engine piston the striker is projected so as to strike gong 1 thus sounding the same. By this means the striker 8 is reciprocated so as to sound the alarm. As clearly illustrated in Fig. 2, and as will be obvious, the striker 8 is a snug lit in cylinder 7 so as to ensure that the striker will be drawn into the cylinder on the suction stroke of the engine piston. This permits the signal to be mounted in any preferred position and ensures proper operation of the striker while avoiding any necessity for providing springs or similar elements for retracting the striker. The device constructed and arranged in this manner may be readily applied to an automobile engine of standard construction without necessitating any material changes therein, and its operation is automatic in that it is operated by the operation of the engine of the automobile. As all parts of the device are of very simple construction it may be readily produced and applied at very small cost.

What I claim is In combination with an internal combustion engine, a cylinder, a striker slidably mounted in the cylinder to be projected beyond one end thereof, said striker fitting snugly within the cylinder, a resonant member positioned to be struck by the striker when the latter is projected, and means for establishing communication between said cylinder and one of the cylinders of the engine tor reciprocating the striker in accordance with reciprocation of the piston in the engine cylinder.

In testimony whereof I afiix my signature.

DAN E. SEEMAN.
